Dr. Gregory Botsaris
Professor, Chemical Engineering (Emeritus), Tufts University
Research Professor, Tufts University
E-mail: Gregory.botsaris@tufts.edu
Education:
Ph.D., Chemical Engineering, M.I.T., 1965
Engineering Degree (Chemical Engineering), M.I.T., 1960
M.S., Chemical Engineering, M.I.T., 1959
B.S., Chemistry, University of Athens, Greece, 1952
Research Interests:
- A New Freeze Concentration Process For Industrial Effluents:
Volume reduction of hazardous industrial effluents by freezing and removing the water as ice. A new process has been developed and tested successfully in our laboratory. The process uses ultrasounds for the nucleation of the ice crystals.
Stability Analysis of Industrial Crystallizers and Dynamic-Behavior Simulation in the Laboratory:
A new laboratory technique was developed to simulate the crystal-size distribution cycling that is observed in large industrial crystallizers. A model explaining the causes of this cycling has been developed and tested successfully in our laboratory.
- Crystallization of Calcium Magnesium Acetate:
Calcium magnesium acetate is a chemical with two major potential uses for solving environmental problems. As a road de-icing salt to replace the corrosive and environmentally unacceptable NaCl. As an additive to the coal combustion where it binds the sulfur and reduces emissions of SO2.
